Computer Memory

Hello,

2GB is 2 "gigabytes". 256MB is 256 "megabytes".

1 "gigabyte" is another way to refer to 1000 "megabytes".

So, 2GB is much more than 256MB!

Hope that helps you out!

First, you have to realize that there are a large range of computers, with a very large range of requirements. Also, the amount of RAM will likely change rapidly in the future.

Most "el cheapos" off the shelf of Wal-Mart have between 512 MB and 1 GB of RAM. A typical desktop sold by, say, Dell or HP will have about 2 GB of RAM. Most computers on the market will support between 4 and 8 GB of RAM maximum.

Software incompatibility is one cause. That includes having two virus programs on your computer.

Other computer freezes may have other causes such as overheating of the CPU because the CPU fan is failing, power supply problems, failing hard drives, and operating system problems.

In Windows, there is the Event Viewer. That is where you can find system errors. You can try copying the text in the errors and search them on the web for possible solutions. A few of the events listed may even tell you how to fix them.

It also depends on what you are using when you experience lockups. If it is in the browser, you may need to reinstall the browser, or you may need to reinstall JAVA or Flash. In rare cases, you may need to find a JAVA or Flash remover before reinstalling those components.

Advanced System settings: To access this location, go onto the specifications page of the computer, (go to my computer, right-click, properties) on the left hand pane you will see "advanced system settings" enter it (you need admin privileges) and then go onto the advanced tab, click the first option, and do what you need to do in the virtual memory!

A PC4000 DIMM chip is better than PC3200 because it runs at higher clock speeds. This results is faster transfer speeds.

Memory modules are used for adding RAM to a computer motherboard. As a standard computer industry practice the motherboard manufacturers do not add RAM to motherboards but provide slots (empty sockets) to which memory modules can be added as per computer configuration needs of the end user. Semiconductor RAM which is manufactured as standard chips is assembled on printed circuit boards as memory modules of different capacities (e.g 512MB , 1GB or 2GB). Examples include SIMM, DIMM, SODIMM. These module printed circuit board size, shape and signals are standard as defined for various memory types e.g. 200pin laptop DDR2 SODIMM is a common laptop memory type these days. Since there are standard modules for all type of computers, for a specific computer type you can just buy memory module and add RAM to the computer.

No. The "byte" is much larger: A "byte" consists of 8 "bits". 4 bytes would equal 32 bits (4 x 8)

The type of RAM you use is dependant on what your motherboard and CPU can handle. You want to change from DDR to DDR2? Id' recommend getting a new computer.

Did you mean: 'How can bytes are in 2 GB?'

If you did, the answer is: 2 Billion Bytes, which transforms into 2 Million Kilobytes, then 2000 MB, eventually reaching 2 GB.

1,000,000,000 B = 1,000,000 KB = 1000 MB = 1 GB

2,000,000,000 B = 2,000,000 KB, = 2000 MB = 2 GB

Basically 1 kilobyte

What do you mean? 1024MB = 1 GB

i think he meant how many gigabits in a gigabyte too which the answer would be 8

well there are

1000 bytes in a kilobyte.

1000 kilobytes in a megabyte.

and 1000 megabytes in a kilobyte.

therefore i would say 3500000000 bytes = 3.5 GB

actually, there are

1024 bytes in a kilobyte

1024 kilobytes in a megabyte

and 1024 megabytes in a gigabyte

therefore 3.5 GB is exactly 3,758,096,384 bytes

"Not Responding" is a status referred to a process or task that stops communicating with Windows operating systems. As a result, it just idles, stuck in some process taking up processing power and RAM.

The size is exactly what it sounds like - the size of the file. The size on disk however is not quite as simple. Before I can answer that, we need to review some file system terminology. I'll be using the NTFS file system in these examples, but the same principles apply for most (if not all) other file systems. A cluster is the smallest amount of space that can be allocated on the file system. Cluster size indicates how large the cluster is. The default cluster size for an NTFS volume for a majority of drives around today is 4KB. The size of the volume does change the default cluster size, but for now, we'll assume 4KB. Let's say you have a file that is 1MB. Now, 1MB = 1024KB. So if we divide 1024 by 4 we will get the total number of clusters this file will occupy on the hard drive. In this case, that number is 256. Since these figures divide evenly with no remainder, the size on disk for this file is also going to be 1MB. Now let's use 1.2MB as our example file size. 1.2MB = 1228.8KB. Again, we'll divide 1228.8 by 4 to come up with 307.2. This means that the file will take up 307 whole clusters, and 20% of the last cluster. Since you can not allocate space smaller than a cluster, the entire cluster is considered to be in use. This is where the size on disk value is important. To calculate the size on disk, we have to round the number of clusters up, and then multiply by the cluster size. We'll take 308 * 4 to get 1232KB. In this case, the size will be 1228.8KB, but the size on disk will be 1232KB. So to summarize, the size value is the actual size, but the size on disk measures the amount of space each cluster of the file is going to occupy.

there is not enough ram installed

1.DMA may lead to cache coherency problems.

2.May lead to bus error interrupt, which arent easy to process.

RAM or Random Access Memory is the computers temporary memory. It is volatile memory and will not provide long term storage for your data. Once power is cut off from the motherboard, the RAM is purged.

If the port on your motherboard is an AGP slot then it doesn't matter if you have ddr or ddr2
